Well if its just aesthetics thats keeps you from putting it in the while loop then any of the above would work... not of fan of the try/except one though. Just know there isn't going to be any performance difference putting it in its own function though. Here's one that I believe also meets your requirements :-)

# you have to define the function first if your while isn't in a function
def UseInput():
   input = raw_input("enter input: ")
   if input == "exit":
      return False
   elif input == "pass":
      return True


   # Do stuff
   return True


while UseInput():
   pass
